is there simple way convert html file perl hash? example working perl modules or something? i search on cpan.org did'nt find can want. wanna this: use example::module; $hashref = example::module->new('/path/to/mydoc.html'); after want refer second div element this: my $second_div = $hashref->{'body'}->{'div'}[1]; # or this: $second_div = $hashref->{'body'}->{'div'}->findbyclass('.myclassname'); # or this: $second_div = $hashref->{'body'}->{'div'}->findbyid('#myid'); is there working solution this? html::treebuilder::xpath gives lot more power simple hash would. from synopsis: use html::treebuilder::xpath; $tree = html::treebuilder::xpath->new; $tree->parse_file( "mypage.html"); $nb=$tree->findvalue('/html/body//p[@class="section_title"]/span[@class="nb"]'); $id=$tree->findvalue('/html/body/

i have following situation want address using python (preferably using numpy , scipy ): collection of documents want convert sparse term document matrix. extract sparse vector representation of each document (i.e. row in matrix) , find out top 10 similary documents using cosine similarity within subset of documents (documents labelled categories , want find similar documents within same category). how achieve in python ? know can use scipy.sparse.coo_matrix represent documents sparse vectors , take dot product find cosine similarity, how convert entire corpus large sparse term document matrix (so can extract it's rows scipy.sparse.coo_matrix row vectors)? thanks. may recommend take @ scikit-learn ? regarded library in python community simple consistent api. have implemented cosine similarity metric. example taken here of how in 3 lines of code: >>> sklearn.feature_extraction.text import tfidfvectorizer >>> vect = tfidfvectorizer(min_

i´m struggling best design activex control in regards registration , reference. one part of our software based on activex controls used on internet explorer , referenced guid, , activex control make connection server , data (live images) it. the problem i´m facing everytime update server version have change version of activex controls because there new codes client, so, activex of version 6.3 example not connect 6.4 server , must updated the thing that, best design have different versions of same activex registered on machine? should change guid of activex every new version??? i have searched lot , couldn´t find satisfactory, , can´t use registration-free com because activex control meant used inside internet explorer

i want uicollectionviewcells have rounded corners , drop shadows have run problem seems can have 1 or other, not both. to round corners use code in initialization of cell: calayer *layer = [self layer]; [layer setcornerradius:4]; [layer setrasterizationscale:[[uiscreen mainscreen] scale]]; [layer setshouldrasterize:yes]; to add drop shadow use code in initialization of cell: calayer *layer = [self layer]; [layer setmaskstobounds:no]; [layer setrasterizationscale:[[uiscreen mainscreen] scale]]; [layer setshouldrasterize:yes]; [layer setshadowcolor:[[uicolor blackcolor] cgcolor]]; [layer setshadowoffset:cgsizemake(0.0f,0.5f)]; [layer setshadowradius:8.0f]; [layer setshadowopacity:0.2f]; [layer setshadowpath:[[uibezierpath bezierpathwithroundedrect:self.bounds cornerradius:layer.cornerradius] cgpath]]; to try , have rounded corners , drop shadow use code in initialization of cell: calayer *layer = [self layer]; [layer setmaskstobounds:no]; [layer setcornerradius:4]; [layer

alright, have strange 1 pick brains about. repository: revision 0: empty revision 1: dir1/f1.txt revision 2: dir1/f1.txt , dir1/f2.txt , dir2/f3.txt your typical, right? now strangeness. svn 1.6.5 , 1.6.13 alike. i'm not going able upgrade try rid of this. i'm running these commands in working copy root. commands svn update -r1 - update revision 1 successful, working copy looks good. svn update --depth immediates - good, dir2 gets created , empty, no other changes. svn update dir1 --set-depth infinity - svn says ok, dir1/f2.txt won't pop in working copy. svn update - cause i'm getting anxious - nothing, dir1/f2.txt still wont pop up. svn update -r1 - error: dir1/f2.txt not under version control (whoa?) svn update - dir1/f2.txt in. if knows why dir1/f2.txt refuses appear when run step 3 , what, if anything, doing wrong, please share. this has been confirmed bug in svn 1.6. resolution upgrade svn 1.7 or svn 1.8. fro
